Patent CA-2080996-A1 (CA)
Title: Laparoscopic hook scissors
Inventor: SLATER CHARLES R
IPC: A61B10/00
Filed: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE    Hook scissors end effectors are provided for a laparoscopic instrument.  The hook scissors end effectors generally comprise first and second blades, with at least one of the blades pivotally engaging the laparoscopic instrument. Each blade comprises an elongate straight blade member with an integral transverse hook element at the distal end of the blade member.  The hook elements each extend towards the other blade member and each hook element is offset from its blade member so that a narrow recess is provided between opposing first and second hook members upon closing of the first and second blade members.  The elongate straight blade members provide a straight scissors cutting action therebetween so that the contiguously adjacent portions of the blade members gradually come together in a continuous bearing contact to effect a cutting action.  While the hook elements at the distal ends of the blades effectively provide a hook which contains the object to be severed, the distal portions of the blade members do not establish contact with each other until the cutting action reaches the distal portion of the scissors.

Title: Method of manufacturing and applying heat treatment to a magnetic core
Inventor: TAKEUCHI MASATO
IPC: H01F1/153
Filed: 1992-03-04
Abstract: A magnetic core having a low core loss and having stable characteristics in a low magnetic permeability region can be obtained at a high yield by applying a heat treatment to a magnetic core main body obtained by winding or laminating a ferrous amorphous ribbon in a wet atmosphere containing a limited amount of steam.  Further, a magnetic core having stable characteristics for the quality of products can always be obtained at a high yield even when magnetic ribbons as the blank have scattering, by adopting a method of applying a heat treatment to the magnetic core main body as described above by measuring the curie point, the differentiated crystallization temperature or the crystallization temperature of optionally sampled amorphous ribbons and comparing the measured value for the temperature with the curie point corresponding to the heat treatment temperature for the previously prepared aimed magnetic permeability, the differentiated crystallization temperature or the crystallization peak temperature, thereby determining an optimum value for the heat treatment temperature.

Title: Guide catheter system for angioplasty balloon catheter
Inventor: ADAMS DANIEL O
IPC: A61M25/06
Filed: 1991-10-28
Abstract: The present invention relates to a guide catheter system (10) for guiding an angioplasty balloon catheter (18) into a patient's vascular system. The guide catheter system (10) includes a guide catheter (12) and a distal guide catheter extension tube (14). The guide catheter (12) constitutes an elongated tube, while the guide catheter extension (14) constitutes a distal, smaller diameter extension for the guide catheter. The guide catheter extension (14) is adapted to extend from the guide catheter (12) to an extent possibly sufficient to reach the stenosis in a coronary artery.  A fixed wire angioplasty balloon catheter (18) is advanced through the guide catheter (12) and guide catheter extension (14) to the stenosis for treatment thereof. Efficient and easy exchange of the balloon catheter (18) is achieved because the guide catheter extension (14) remains in place when the balloon catheter (18) is withdrawn proximally, so that a path remains to guide another balloon catheter (18) to the stenosis for treatment thereof.

Title: Sample evaluation by dust measuring
Inventor: SIOMA EDWARD M
IPC: G01N15/06
Filed: 1993-06-15
Abstract: ABSTRACT OF THE DISCLOSURE A tubular test chamber of square cross-section minimizes reflection of stray light from the interior surface of the test chamber onto the detector during measurement by an optical system which is based upon right angle light scattering by the dust particles of a test sample. A rotary solenoid is utilized to open a trap door through which a sample is dropped into the test chamber during energization so that the internal spring of the solenoid can be used to bias the door closed upon deenergization thereof. The electronic circuitry which supports the measurement process provides an output in the form of a single "characteristic number" for each sample measured and has a novel feedback circuit used in auto-zeroing of the device.

Title: Safety device for vehicle electric openers, particularly window lifters and sunroofs, and opener incorporating this device
Inventor: HECKEL ROBERT J
IPC: B60J1/17
Filed: 1993-07-08
Abstract: ABSTRACT         This device comprises mechanical means including a pawl (25) establishing a rigid drive link between a driving  input  member (2)  and  an  output  member (22), interacting with a prestressed element (31) which tends to hold the pawl in connection with the driving input member or with the driven output member, for so long as the force transmitted by the pawl remains below a prede-termined value; this system automatically interrupts the kinematic drive chain of the movable member in the case of a force exceeding a predetermined value. This arrange-ment makes the device practically insensitive to friction and eliminates the uncertainty on the threshold of the triggering force.

Title: Universal tined myocardial pacing lead
Inventor: STOKES KENNETH B
IPC: A61N1/05
Filed: 1993-09-15
Abstract: ABSTRACT      A myocardial pacing lead include  two sets of at least two tines placed to oppose each other.  The lead is pressed against the epicardium and is rotated until a rough porous tip abrades the epicardium and allows the tip and the first row of tines to penetrate the myocardium.  Excessive penetration and lead migration is prevented by the second row of tines which is mounted backward and just proximal from the first row of tines.  The first row of tines anchor on the inside surface of the epicardium which prevents dislodgment.  Dacron pads on the second row of tines assures chronic fixation by adhering to the outer surface of the patient's epicardium.
